How to avoid storing in the database if an error occurs in the next iteration step
Input data is a list of dictionaries. The list can consist of several hundreds of dictionaries and looks like this. data = { "vendor_name": "Ullamcorper Duis LLP", "country": "Belgium", "nda": "", "modules": [ { "module": "" } ], "contacts": [ { "email": "jack@gmail.com", "contact_name": "Jack Jhonson", "primary": true }, { "email": "jack2@gmail.com", "contact_name": "Jack Jhonson", "primary": false } ] }, { "vendor_name": "Habitant Associates", "country": "Turkey", "nda": "", "modules": [ { "module": "" } ], "contacts": [ { "email": "eget.metus.eu@elitdictum.edu", "contact_name": "Trevor Smith", "primary": true }, { "email": "at.risus.Nunc@iaculis.ca", "contact_name": "Madonna Z. Kemp", "primary": false } ] }, .... .... ] Since some fields (for example, vendor_name) must be unique and if n-element and n+1 item are equal, the error "Vendor already exists" appears. And this is correct, of course. It so happens that some information is written into the database before the error occurs. But I need the writing to be done on the all or nothing principle. views.py class CsvToDatabase(APIView): serializer_class = VendorsCsvSerializer def post(self, request, format=None): r_data = request.data for data in r_data: if data['nda'] == '': data['nda'] = None for contact in data['contacts']: if contact['email']: contact['email'] = contact['email'].lower() for module in data['modules']: if module['module']: module['module'] = … -
Render HTML for REST API JSON data
What tools/solutions available for rendering html after REST API call returns JSON data? I have a Django webapp, where I built a set of REST API common for processing all data through the UI/browser or mobile app. The API will only return JSON, no HTML. I want to be able to draw tables, and do other HTML things on the browser-based on the data returned by the API, I cannot retrieve, or be loading html before the API calls. Do handlebars etc work in this situation? What are other effective options? -

Strange non-breaking space when copying text from website in Chrome
I am developing a website in Django. It is a movie database. For creating a movie reference, I am using a join function like this: ''.join(i for i in movies) As a result, I get the following references for movies: Titanic. Directed by <i>James Cameron</i>. 1997. Everything is perfect on the backend side. On the frontend side, everything is visually OK, but when I copy the string with the movie reference and paste it into Microsoft Word, a non-breaking space appears before the italicized item instead of the regular space (I've tried italicizing other items as well, and it appeared everywhere before them): Titanic. Directed by°James Cameron. 1997. I do not add any non-breaking spaces, and I've tested out the backend side, no nbsp's appear there. Moreover, when I inspect the page in Chrome... it shows no non-breaking spaces: Titanic. Directed by <i>James Cameron</i>. 1997. How come that it appears on copying? And how can I avoid this behavior? P.S. I've tried this out on the book referencing site https://www.citethisforme.com/, and it's all the same. When adding a journal, this non-expected nbsp appears right before the italicized journal title element. -

Heroku cannot read '/etc/secret_key.txt', No such file or directory:
I successfully deployed a django app to heroku with my settings.py as such: SECRET_KEY = 'the_real_long_secret_key_itself', which of course is not recommended, but that was find for me just in this scenario as it is just a test and can be changed. Now back to my local environment, I decided to hide the key without changing it yet and according to django documents like this: # on settings.py with open('/etc/secret_key.txt') as s: SECRET_KEY = s.read().strip() And it works when I run server locally.

Django change choice before validation
I am trying to update a choice field before it is validated in Django. The reason for this is the choice field in question value is the Id of a model that i want to update. def fuelLogSystemOne(request): entries = FuelLogSystemOneMod.objects.all().order_by('date') products = productsMod.objects.all() if request.method == 'POST': form = forms.AddFuelLogOneForm(request.POST, request.FILES) productid = form['product'].value() product = productsMod.objects.get(id=productid) product_id = request.POST.get('product') form.fields['product'].choices = [(product.product_type, product.product_type)] if form.is_valid(): bucketsRemoved = form['buckets_added'].value() product.stock -= bucketsRemoved product.save(['stock']) instance = form.save(commit=False) instance.staff = request.user instance.save() return redirect('home') else: form = forms.AddFuelLogOneForm() return render(request,'systems/fuellogsystemone.html',{'form':form,'entry':entries,'products':products}) The below part is where i am trying to change the form data before it gets validated so it doesn't say 'Select a valid choice. 1 is not one of the available choices' product_id = request.POST.get('product') form.fields['product'].choices = [(product.product_type, product.product_type)] But when I first submit the form it is still saying 'Select a valid choice.' At what point does Django validate the form because I am changing the form before the is_valid() method and it still hits this error? -
Django REST Framework - cookies not being set via Response.set_cookie() call...?
I have the following standard Response setup in my DRF application: response = Response(data=response, status=status.HTTP_200_OK) I'm then attempting to add a split JWT header.payload and signature to the response headers with a response.set_cookie() call, as follows: max_age = 365 * 24 * 60 * 60 expires = datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age) response.set_cookie( key='JWT_ACCESS_HEADER_PAYLOAD', value=header_payload, httponly=False, expires=expires.strftime("%a, %d-%b-%Y %H:%M:%S UTC"), max_age=max_age ) response.set_cookie( key='JWT_ACCESS_SIGNATURE', value=signature, httponly=True, expires=expires.strftime("%a, %d-%b-%Y %H:%M:%S UTC"), max_age=max_age ) return response I can't see anything wrong with what I have done thus far: Yet, for some reason, the only cookies set on the client side are as follows: What have I done wrong here??

Manage models inheritance in Django admin
I'm developing with my team a Django webapp which provides authentication and users profile creation. Basically, we are dealing with a model Profile which extends django.auth.contrib.models.User implementing One-to-One link method, as shown below model.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) birth_date = models.DateField(default=datetime.date.today) # other custom fields def __str__(self): return self.user.username Since we have registered the model in admin.py, it appears in Django admin panel, as it should be. Then, we have introduced another model PersonalTrainer which is an intherited class of Profile one. admin.py from django.contrib import admin from usermanager.models import Profile, PersonalTrainer admin.site.register(Profile) admin.site.register(PersonalTrainer) Is there any programmatically method to organize PersonalTrainer instances in a such a way they appear both in Profile section and PersonalTrainer section? In other words, we'd like to have a PersonalTrainer instance which appears in auth User model, Profile model and PersonalTrainer model. -

How can I convert my class-based view to function-based views? - Django

Object level authorization in a Django Rest Framework viewset
I'm creating an API with Django Rest Framework (DRF) and wondering where I should handle object level authorization. So far I've created an Organization model and a custom user model with email being the unique identifier instead of username. Organizations and users are currently connected through a many-to-many field. What I'd like to do is make sure that when a user hits my API they're only able to do the standard CRUD actions on the models that are linked to the users respective organization. As an example here's my current UserViewSet where I've overriden then get_queryset method to filter the User queryset to only return other users who are apart of the same organizations as the user calling the API: class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer def get_queryset(self): User = get_user_model() user = self.request.user organizations = user.organization.all() return User.objects.filter(organization__in=organizations) What's considered best practice to extend these limitations to other viewset actions? For example, if I want to make sure that the user can only create and add other users into the organizations they're linked to, should I override the create method in the viewset and perform a validation there that the organization which was passed in the request data is the … -

Add extra non-model attribute to serializer

In my webapp, I have a friends feature, but one of the if statements produces an error Here is my UserProfileInfo model class UserProfileInfo(models.Model): connection = models.ManyToManyField(User,blank=True,related_name='follow_profile') And now here is my view: def friend_actions(request,username=None): current_user = request.user.userprofileinfo user = request.user # username = get("username") username = User.objects.get(username=username) other_user = get_object_or_404(UserProfileInfo,user__username=username) # other_user = UserProfileInfo.objects.get(username=username) url = other_user.get_absolute_url() if other_user in current_user.connection.all(): current_user.connection.remove(other_user) else: current_user.connection.add(other_user) return HttpResponseRedirect(url) However, this produces the following error: argument of type 'QuerySet' is not iterable Full traceback Traceback: File "C:\Users\User\.virtualenvs\interests-site-Ho6yLlHE\lib\site-packages\django\core\handlers\exception.py" in inner 34. response = get_response(request) File "C:\Users\User\.virtualenvs\interests-site-Ho6yLlHE\lib\site-packages\django\core\handlers\base.py" in _get_response 115. response = self.process_exception_by_middleware(e, request) File "C:\Users\User\.virtualenvs\interests-site-Ho6yLlHE\lib\site-packages\django\core\handlers\base.py" in _get_response 113. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\User\interests-site\interests-drf\mainapp\views.py" in friend_actions 453. if other_user in current_user.connection.all(): Exception Type: TypeError at /mainapp/profile/donnellan0007/connect/ Exception Value: argument of type 'QuerySet' is not iterable I am wondering how I can stop this error from occurring. I have been stumped by it all day -
